Some decisions seem easy, like giving the ball to your monster running back when it's 3rd and goal from the 1 yard line instead of passing... right? But then again if the pass works, the coach is a genius, creative, and three strategic moves ahead of his opponent. It's the classic sports conundrum, but sometime the simplest strategy is the best course of action. The same logic applies to Kaufman trailer axles, keep it simple when considering this strategic move.
Do you go with twin 10,000 lbs dually axles, or three 7,000 lbs single wheel axles when deciding the type of trailer to configure in your Hotshot set-up? Don't over think this decision. If your building a set-up to run under 26,000 GVWR go with the tri-axle configuration, if you're a Class-A CDL driver running a set up over 26,000 GVWR, get the twin 10,000 lb duallys. It's really that simple.
The decision boils down to the dry weight between the 2 set-ups. The tri-axle dry weight configuration will run at least 500 lbs lighter than the twin dually's. When setting up a hotshot rig to run under 26,0000 the dry weight of your truck and trailer is a critical issue. The higher the dry weight (no load on the trailer) the lower the payload. To maximize your payload under 26,000 GVWR, the equipment selection should be deeply centered around keeping the dry weight low. This is the same reason running a 4-wheel drive truck is a huge mistake under 26,000 GVWR. There are operating difference between the tri-axel and twin dually's to consider, but the weight difference is a trump card in the decision, and over-rides ALL of the operational advantages one might argue in favor of the twin dually's.
So keep it simple. If your running under 26,000 GVWR, a tri-axel trailer is like handing the ball off to your unstoppable running back on the 1 yard line, getting a trailer with twin dually axels under 26,000 is like passing from the 1, it might work some days.... but you could end up looking for another job.
